The Exchange Support component in Apple iPhone OS before 3.1, and iPhone OS before 3.1.1 for iPod touch, does not properly implement the "Maximum inactivity time lock" functionality, which allows local users to bypass intended Microsoft Exchange restrictions by choosing a large Require Passcode time value.
The product contains a concurrent code sequence that requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence operating concurrently.
